discovery of america. and we discovered america for ourselves. we knew about america, but what we knew, america very different. we knew something that we learn from the 19th century america. and then this new world and we tried to find out how books, i found this book very interesting, but i just wanted detail of this book of the story, but from that aside, my first wish, was what you wrote this book. 50 years ago, visit from one leader of one country to the united states. i think there may be other leaders came here. sometimes khrushchev was eccentric. and president yeltsin was more eccentric, and when khrushchev came here, he just showed the time like this contemporary politician that we prefer to go to the common show, because most of the young people interest in this, maybe it was part of this. my father's behavior. maybe it was because it was back through the old war mentality on both sides, but not eliminate at that time in one visit, but it would change so why you wrote this? >> guest: i wrote the book because i happen to stumble upon the story of your father, nikita khrushchev'
